从日期范围中删除周末

Question

我有一系列的日子需要确定周末是否在这个范围内。如果是这样，我将在最终范围内添加 2 天（周一至周日，将其更改为周一至周三。（基于用户选择的天数，例如 5）我已经找到了一种解析日子的方法（不确定这是否是最佳实践）并且不确定如何继续。迄今为止：////TODO Refactor to new classDateTime startingDate = DateTime.Parse("07/25/2018");//TODO Insert variable from poted form DateTime endingDate = DateTime.Parse("07/08/2018");//TODO Insert variable from posted form var days=  Enumerable.Range(0, 1 + endingDate.Subtract(startingDate).Days)                .Select(offset => startingDate.AddDays(offset))                .ToList();在我看来，我需要像下面的伪代码那样做：if day.contains dayOfWeek.Saturday ||Or dayofWeek.Friday {Add.Days(2)}但我不知道如何。

Answer 1

第一个你计算所有的周末天数。然后，将结果添加到开始日期中。这是我的解决方案。希望能帮到你，朋友！

static IEnumerable<DateTime> GetDaysBetween(DateTime start, DateTime end)

        {

            for (DateTime i = start; i < end; i = i.AddDays(1))

            {

                yield return i;

            }

        }

DateTime startingDate = DateTime.Parse("07/25/2018");//TODO Insert variable from poted form 

var numOfWeekends = GetDaysBetween(startingDate, startingDate.AddDays(7))

            .Where(d => d.DayOfWeek == DayOfWeek.Saturday || d.DayOfWeek == DayOfWeek.Sunday).Count();

startingDate = startingDate.AddDays(numOfWeekends);

            Console.WriteLine(startingDate);

Answer 2

我并没有真正理解附加部分，但是此代码将为您提供一个没有任何星期日或星期六的列表：

DateTime startingDate = DateTime.Parse("07/25/2018");//TODO Insert variable from poted form 

DateTime endingDate = DateTime.Parse("07/08/2018");//TODO Insert variable from posted form

List<DateTime> dates = new List<DateTime>();

for (DateTime dt = startingDate; dt <= endingDate; dt = dt.AddDays(1))

    if (dt.DayOfWeek != DayOfWeek.Saturday && dt.DayOfWeek != DayOfWeek.Sunday)

        dates.Add(dt);

如果需要，您还可以添加计数器：

DateTime startingDate = DateTime.Parse("07/25/2018");//TODO Insert variable from poted form 

DateTime endingDate = DateTime.Parse("07/08/2018");//TODO Insert variable from posted form

List<DateTime> dates = new List<DateTime>();

int couter = 0;

for (DateTime dt = startingDate; dt <= endingDate; dt = dt.AddDays(1))

{

    if (dt.DayOfWeek != DayOfWeek.Saturday && dt.DayOfWeek != DayOfWeek.Sunday)

        dates.Add(dt);

    else

        counter++;

}

或者别的什么...
